Crystalline silica exposure - WorkSafeBC

Crystalline silica is a naturally occurring mineral most commonly found as quartz. It is found in substantial quantities in sand, sandstone, granite, stone and rock aggregates, clay, shale and slate. When crystalline silica is released in the air as a fine dust, workers may inhale the dust, which puts them at risk for illness.

Dust Including Silica Dust - Health and Safety Authority

Dust is produced in the quarrying process while it is being blasted, crushed, screened, transported and stored. There are three ways that you can manage dust: 1. Contain it, 2. collect it, or. 3. suppress it. The Pareto principle (or 80-20 rule) applies to quarry dust generation. "Eighty percent of the dust in a given quarry is generated by 20% ...
